Definitions

  • the invention relates to a sealed connecting device between two housing faces according to claim 1.
  • a sealed connecting device between two housing end faces with a plate-shaped intermediate part, in particular a plastic brush support plate in the plane of the housing end faces, is to be created, which is easy to manufacture and assemble in an advantageous manner for an inexpensive series use, and nevertheless one full immersion tightness, in particular also in the case of external connecting lines carried out in the area of the connecting device, is guaranteed.
  • the connecting device on the one hand allows the seals to be produced by spraying and vulcanizing, regardless of the intermediate part which will later support them, and regardless of the otherwise necessary high heat resistance, and allows the sealing ring body to be fitted onto the intermediate part in an assembly and production technology manner in an advantageous manner sealing push-through of the connecting lines through the sealing hoses molded onto the sealing ring body, so that the implementation of the connecting lines in the area of the sealing surfaces pressed against the housing faces remains without influence on the squeezing behavior of these sealing surfaces and thus a uniform sealing over the entire sealing surface is ensured.
  • the connecting lines expediently consist, at least in the area of the sealing arrangement of the sealing tubes, of insulated elastic cable lines which, according to a further embodiment of the invention, are connected with an inner stripped end to contact lines of the intermediate part, which is expediently designed as a brush support plate of a commutator motor.
  • the intermediate part is provided with an embedded ventilation duct leading from the inside of the motor housing to the outside, which, like the connecting lines, extends radially outside the sealing contact area of the housing end faces him sealingly fitting, molded on the sealing ring body sealing tube is inserted, so that also in the area of the ventilation duct a uniform sealing system between the intermediate part on the one hand and the axially abutting motor housing or pump housing can be guaranteed.
  • the intermediate part is used for the sealed connection not only as a suitable supporting part for the sealing ring body which can be clamped onto its outer edge and as a brush support plate when using a commutator motor to be connected to a second housing, but also for alignment and sealing on the shaft side of the commutator motor when it is connected at the front the further housing, in particular a pump housing, is used in that the motor rotor shaft end is mounted on the commutator side, centered directly in a bearing seat of the further housing, by means of a fixed rotor shaft bearing, and the brush support plate, which is fixed relative to the motor housing, bears radially sealing against the motor rotor shaft end.
  • FIG. 10 shows, for an introductory explanation, in an axial partial longitudinal section, a motor-pump unit with a cup-shaped motor housing 1 of a commutator motor, which with its cup edge 1.3 rests sealingly against a pump housing 4 on the face side and can be screwed to it, for example.
  • Excitation magnets 1.1, 1.2 are attached to the inner circumference of the motor housing 1 for magnetic excitation.
  • On the pot edge 1.3 of the motor housing 1 is an intermediate part, preferably a plastic injection molded and in particular essentially plate-shaped brush support plate 3, which is provided at least at the edge on both end faces with a preferably elastic sealing pad 3.1 such that when screwing the motor housing 1 against the Face of the pump housing 4, both components are sealed against each other in a moisture-tight manner.
  • this sealing pad 3.1 is to the Injection molded in the form of the brush support plate 3; Although such a seal ensures a high immersion tightness, this manufacturing process requires high heat resistance of the intermediate part and requires long holding times of the entire intermediate part.
  • the rotor shaft 2 which accommodates a commutator 2.2 and a rotor sheet metal package 2.3 with a rotor winding 2.4, is mounted at its left end in a spherical bearing provided as a B-side rotor shaft bearing 5 and at its right end in a ball bearing provided as an A-side rotor shaft bearing 6.
  • the commutator motor is advantageously designed as a preassembled component unit with a brush support plate 3 which is axially fastened to the open side of the motor housing, in particular - as can be seen in FIG. 8 - by means of latching means 1.5 distributed over the circumference and provided with sealing supports 3.1, and with the axially outside in front of the brush support plate 3 centered on the rotor shaft end 2.1 in the tight fit A-side rotor shaft bearing 6 to the pump housing 4 in its bearing receptacle 4.1 axially inserted.
  • the preassembled motor component unit is supported radially sealingly via its brush holder 3 on the A-side rotor shaft bearing 6 and thus the bearing holder 4.1 of the pump housing 4 and can thus overall with an axial plug-in assembly between the motor housing 1 on the one hand and the pump housing 4 on the other hand before the final mutual flange connection be centered; in the embodiment shown in FIG 10, the immediate centering to the pump housing 4 via the brush support plate 3 and the rotor shaft 2, on which the brush support plate 3 is centered and sealingly with a cutting-shaped contact edge 3.5; due to the cutting-shaped contact edge 3.5, on the one hand a low frictional resistance and on the other hand a good seal is achieved in such a way that any pump leakage liquid which may escape cannot get into the interior of the motor housing 1.
  • the mutual switching connections between the components or contacts to be received by the brush support plate 3 are advantageously in the form of a lead frame 8 cast into the brush support plate 3 such that, in particular on the sealing contact edges between the motor housing 1 on the one hand and the pump housing 4 on the other hand, the lead frame Connections are embedded on both sides in the plastic base body of the brush holder 3, in particular injected. As can be seen in particular from FIG.
  • an axially projecting plug-in contact 8.1 is integrally formed for connecting connecting lines, in particular control lines, with switching connections of the brush support plate 3 to the lead frame 8, which protrudes axially from the brush support plate 3 into a, preferably axially extending contact opening 4.2 in the Pump housing 4 protrudes in such a way that counter-contacting can take place from a control unit, not shown here, on the end of the pump housing 4 facing away from the motor.
  • the brush support plate 3 which lies sealingly between the parts of the motor housing 1 on the one hand and the pump housing 4 on the other hand, is provided with a ventilation channel 3.2 leading from the inside of the motor housing 1, which is preferably cast radially into the brush support plate 3 is.
  • a ventilation channel 3.2 leading from the inside of the motor housing 1, which is preferably cast radially into the brush support plate 3 is.
  • Moisture in this ventilation channel 3.2 is integrally formed on the sealing support 3.1 applied on the edge of the brush support plate 3, which covers the outlet opening of the ventilation channel 3.2 to the open axial and radial motor side.
  • the radially inner end of the ventilation channel 3.2 to the interior of the motor housing 1 is closed off by a membrane seal 3.3, which on the one hand allows ventilation from the inside of the motor housing 1 to the outside Ingress of moisture from the outside into the interior of the motor housing 1 is prevented.
  • FIG. 1-7 show examples of the embodiment according to the invention with a sealing ring body 9 manufactured as a separate individual component and stretched over the outer edge of the intermediate part, in particular the brush support plate 3, which at the same time for the sealing lead-out of external connecting lines 7 and 8, in particular feed lines, in the area of the sealing level serves.
  • a sealing ring body 9 with a substantially U-shaped cross-section is used to seal between the axially mutually sealing end faces, which extends over the outer edge of the brush support plate 3, in particular after the outer connecting lines 7; 8 have previously been stretched through and, if appropriate a vent pipe 3.2, can be tensioned.
  • sealing hoses 9.1 and 9.2 Formed in one piece on the outer circumference of the sealing ring body 9 are sealing hoses 9.1 and 9.2, respectively, such that before the sealing ring body 9 is clamped onto the outer circumference of the brush support plate 3, outer connecting lines 7 or the ventilation pipe 3.2 can be pushed through with tight contact with the sealing hoses 9.1 and 9.2.
  • the outer connecting lines 7 are with a radially inner stripped end 7.1 with lines of the brush support plate 3, e.g. by soldered connection, contacted; the lines of the brush support plate 3 are expediently designed as a lead frame 8 cast into the brush support plate 3.
  • the contact point can - as shown in FIG 5 - radially below or - as shown in FIG 6 - radially above the sealing contact of the motor housing 1 on the one hand and the pump housing 4 on the other hand on the outer edge of the brush support plate 3.
  • the inward outer connection line 7 or the further outward inner line of the lead frame 8 is embedded in the brush support plate 3 in such a way that there is no change in strength in the area of the leadout of the connection lines and thus no different squeezing behavior of the Sealing ring body 9 must be feared but a uniform strength of the seal is guaranteed over the entire seal edge.
  • the brush support plate is advantageous not only for actually receiving and contacting the power supply means to the commutator, but also for the embedded routing of connecting leads and in particular also for uniform sealing over their entire outer edge and by means of the cutting-shaped contact edges 3.5 on their inner shaft on the rotor shaft side with simultaneous centering of the preassembled motor assembly in a bearing seat of the pump housing 4.
